Viktor Valquist and Jesper Sandstrom have been inseparable for years. Not only do they live together, town residents often see them walking in the park, out at restaurants, or touring the museum together. Now that Viktor has adopted a daughter, Linn Valstrom, their home is full of happiness and joy.
Jesper and Viktor are BFFs in-game, and have been inseparable for years. They are often seen in the town, walking in the park, going to restaurants, and touring the museum. They are strongly implied to be in a romantic relationship. Evidence of this can be seen in their pose in family portrait (normally used by married/dating Sims), and Linn's last name is a portmanteau (Valquist and Sandstrom) of their last names, which couples often name their child.
